Oil Filter threads

[spasm3]

Before i install a new filter i wipe the threads by spinning the filter while holding a cloth or towel against the threads. I usually get a gray result on the towel , somtimes a few small bits of metal show up. I do make sure there is no lint on the threads aftewards before filling it and spinning it on.
I've seen this on motorcraft filters m1 filters, just about any filter i've used.
Anyone else notice this?

I do that very exact same thing :^)

We have discussed this before. Around here Purolaters are by far the worst for this. Guess who has the least amount of scrap metal around their threads?

I had that happen the last time I changed my oil. I still lose sleep over it ever now and then. Im not sure I got all the shavings off and think one might have fallen through the threaded hole. I shook it around upside down but couldn't tell if anything came out. I had already removed the old filter and drained the oil so I was kind of SOL. I guess I will see in the oil analysis report if it did anything. Or if a shaving even went through at all. It's time to change it again so I guess I'll find out.

I've never thought to wipe the threads. I do lube the seal with a wipe of new oil, though. After reading these posts I will be using a lint free cloth to wipe it first, going forward though.

Vacuum cleaner on the center hole will suck out any loose shavings inside the center tube.

I like the shop vac idea

That's some crazy [censored].....I don't have much experience with other filters (only ever used FRAM XG/TGs....or ST) but never noticed this.....

I'd think this would be an issue that needs to be raised to hte filter manufacturers, they need to add a filter clean out process (shop vac type, or even [censored] loads of air blown into the filter (though that might mess with the filter media....I suppose?) but the shop vac idea would probably better off....

Works good ... only a real BITOG manic would think of this.

I've never noticed metal on Donaldson, but the brown or gray can be the anti-corrosive they put on the steel so it won't rust.

Another idea is giving it a blast of canned air. Never envisioned doing this before, but I prefer to install a new filter free of metal shavings and debris, and if that's what it takes...

So metal on the threads is good?

Here is a video clip showing the manufacturing of a Fram filter. As you can see, they thread the "capping plate" using a conventional tapping die. It isn't surprising that you will get some shavings on occasion. And I don't see any step that wipes the threads!

I once found metal slivers around the threads of an M1 filter. I called Champ Labs and they said that they use a high pressure wash to clean the threads and plate before it is assembled onto the can. They requested the batch number, etc. I guess it depends on their quality control. I always wipe mine with a paper shop towel to remove any residue.
